2Na + Br2 -> 2NaBr
Br is a diatomic element so the 2 is a subscript, not a coefficient.
Answer:
Los parámetros dados del movimiento son;
La velocidad con la que el atleta se dirige hacia la línea de salida = 6 m / s
El punto en el que se inicia el cronómetro = marca de 100 m
La ecuación para la distancia recorrida, 's', se da como sigue;
s = 6 m / s × t
La distancia total recorrida, d = 100 + s
∴ d = 100 + 6·t
Los gráficos de las ecuaciones se crean con Microsoft Excel y se presentan de la siguiente manera;
Explanation:
The electric potential due to ammonia at a point away along the axis of a dipole is 1.44 10^-5 V.
<u>Explanation:</u>
Given that 1 D = 1 debye unit = 3.34 × 10-30 C-m.
Given p = 1.47 D = 1.47 3.34 10^-30 = 4.90 10^-30.
V = 1 / (4π∈о) (p cos(θ)) / (r^2)
where p is a permanent electric dipole,
∈ο is permittivity,
r is the radius from the axis of a dipole,
V is the electric potential.
V = 1 / (4 3.14 8.85 10^-12) (4.90 10^-30 1) / (55.3 10^-9)^2
V = 1.44 10^-5 V.
Since you didn't include the options, I will answer the question as well as I can: the one factor I would be considering is whether the journal is known to be biased, for example whether it's a peer-reviewed journal ( those are less biased) or whether they journal is paid by some interest group.
Otherwise I would look at whether the data is reliable, for example whether the author cites the sources for their data
